40 legs on the pin plate, which is what happens in mass production of the plug to a considerable extent

The invention relates to a connector for a saving in manufacturing costs leads,
Movable electrical cable with a plug-in It not only does not have to be attached afterwards

pin plate can be snapped into a one-piece housing, the clamping leg on the plug pin plate, but with two by means of film hinges against each other 45 according to the invention is only a single molded part, pivotable clamping legs made of flexible insulation and thus only a single injection mold for the filler material that is removed from the plug pin plate it is necessary to carry the pin plate and the clamping legs and pivot them against each other between them. Nevertheless, the advantages realized with the older pre-pressing of the electrical line, retaining the tensile strength, are also present with the inventive latching elements in corresponding mating connectors,
elements can be snapped into the housing. Although it is already known, a flat connector

It is known (DT-Gbm 1 793 354) to produce latching elements connected to the outer housing halves by means of a film hinge with which they are designed in (GB-PS 863 386). Similarly, a speaking counter-element of the one-piece housing 55 protective contact plug is already known (DT-Gbm 69 16 076), the plug can be locked in place. The conductive wire which has a plug pin plate and on both sides it has at diewird case between a central projection of the _S-faceted via parallel film hinges, together connector plate and an inner annular neck menklappbare housing halves.
